- This inventionwrelates to a heating system for houses, and more: especially a hot air heating system in which a' furnace and an open hearth fireplace have acooperative relationship.

This invention contemplates a-- heating systern" employing an opezi hearth fireplace positimed and designed to directlyaid inthehe'at- 'ing of a house, either in conjunction with, or independently of thefurnaceproper.

. A further object, of this invention resides in utilizing a large portion: of fireplace heat nor: mally transmitted-through the flue.

The foregoing, as. well as further-objects of the invention, will be made more apparent as the description proceeds; 1

- Fig. 5 is a cross-section taken on lines 5-5 of Fig. 2.

Referring to the drawings more in detail, with particular reference to Figs. 1 and 2, it will be seen that a hot air furnace I is shown having an outercasing II connected to a plenum chamber l2, and an open hearth fireplace I3 associated with said chamber. .The invention resides in this About the furnace is located a metal casing l l.

This casing confines the hot air arising from furnace and directs it into the plenum chamber l2. We prefer to locate the plenum chamber directly above the furnace, and to construct it of light sheet metal sections secured together as at H. This chamber extends directly from the top portion l8 of the casing I I, up through the building to the uppermost fioor, so that hot air passes directly throughit, as shown by the arrows to the individual vents I9.

Located above the furnace is the fireplace [3 having a hearth supported upon cross bars -2l. We have shown thebars as havin the ends the walls 26 and 21 of thevfireplace.

thereof at the rear side of the furnace supported from the basement floor by means of vertical Stan'ch'ions- 2 2 Theforwar'd e'n'd's'of the b i rests upon r-bejam 24% Upo'n' thesebars: a metal framework 25 isplaced', to whicli t'he side walls 26 and the backwall 21. of the 'i" epia'ce [3* are firmly'sec'ured by welding or 'the l e. This part framework 25 provides theba'se oE-tl'ie hearth-Z0 which is nerein snown compnsing" fireproof tile '28 secured-in a: filler cement 29.

' At tlie to "portionscf the wailsyzd issecured a pyramid-she. 'd sheet metal need 30 having a front portion of the. fireplace prop'eri A glip 3 2 extends cut wa-rdly from the lower e'd'gtfifl oi the front per: tion to support: a: tilesfacing: .3 2. Between this facing. and the hood: frontis an-aiir space an insulating guardi-fili arid a: sheet metal 'f'dlhi 31 to which the tile facing 34 is secured by cement or the like. This air space is employed because that front portion of the fireplace receives a large amount of heat and if that heat is not transmitted to the plenum chamber but allowed to radiate directly into the walls around 1 the fireplace, in time it would'dry out the cement filler which holds the tiling and also injure painted portions around the front of the fire- 7 place proper.

Associated with the back of walls 26 and 21 is a baffle 38 also U-shaped in cross section. The

I actinglas a frontwall, I

bottom portions 39 of the baffie are open so that a part of the air passing from the furnace to the rooms will be forced into intimate contact with the walls 26 and 27. the baflie opens into the plenum chamber through the top side portions, 44 thereof.

A dome 39 is secured to the top of the back wall'Ml of the baffle 38 and to the top ofthe hood 30. The dome is connected to a fiue M by means of a conduit 42 for the disposal of products of combustion. Upon the upper portion of the hood a damper unit 3!) has been secured for controlling. the draft from the fireplace to the flue 4|.

When the fireplace is, in use, the air in the restricted portions 43 is heated by radiation from The additional air in the plenum chamber is heated by rafdiation from the hood front 3|, the dome 39, conduit 42, which are entirely encased in the The upper end of allow the hot air to expel into the various rooms. These vents may be closed individually so that one or more of the rooms may receive the hot air from the plenum chamber. Thus if only one or two rooms are desired to be heated, the fireplace may be used for that purpose, and when both the fireplace and furnace are in operation, the heating qualities of the fireplace will allow the furnace to be shut down so that it does not operate unnecessarily.

When a fan such as 45 is used with the furnace, the fan thermostat control may be located in the plenum chamber as at 46, instead of on the furnace, as this point will be the hottest when the fireplace is operating. Thus when the fireplace is in operation and the temperature of the plenum chamber reaches a designated degree, the fan will be shut off so as not to burn fuel unnecessarily.

Provision'has been made in the rear portion of the hearth for disposal of ashes through a chute 41, which is also of sheet metal construction and is shown as extending from the fireplace through the upper portion of the furnace casing to the basement. A tiltable plate 48 closes the upper end 49 of the chute and a door 50 seals the lower end of the chute.

From the foregoing description, it will be apparent that numerous modifications may be made within the scope and purview of the description in .the appended claims.

What we claim as our invention is:

1. In a heating system for a house having a plurality of rooms, a furnace, a plenum chamber associated with the furnace for the passage of hot air to the rooms, a supplementary unit for directly heating the air in said chamber, said unit comprising an open hearth fireplace having heat radiating walls and a heat radiating dome portion both within said chamber, sealing the hearth of the unit from the chamber.

2. In a heating system for a house having a plurality of rooms, a furnace, a plenum chamber extending from the furnace including a vertical column communicating with an upper portion of the house adapted to be heated by said furnace, an open hearth fireplace located above said furnace and having back and side plate like heat radiating wall portions extending into said chamber for directly heating the air in the latter by said heat radiating walls.

3. In a heating system for a house having a plurality of rooms, a furnace, a plenum chamber above the furnace for the passage of hot air to the rooms, an open hearth fireplace located above said furnace, having common wall portions with the chamber, and means spaced from said wall portions in the chamber for directing a portion of the air therein into intimate contact with said common wall portions.

4. In a heating system for a house having a plurality of rooms, a furnace, a plenum chamber associated with the furnace for the passage of hot air to the rooms, an open hearth fireplace above the furnace having heat radiating wall portions within said chamber, and a baflie located within the chamber cooperating with said walls to direct a portion of the air in the chamber into intimate contact with said walls.

5. In a heating system for a house having a plurality of rooms, a furnace, a plenum chamber above the furnace for the passage of hot air to the rooms, an open hearth fireplace located above said furnace having back and side heat radiating wall portions acting as the front wall portions of said plenum chamber where the latter contacts said fireplace, whereby substantially all of the air heated by said furnace passes about said fireplace wall portions.
